They could get someone to drop by and feed the dog a time or two a day for fairly cheap. Their house is apparently one they list on air b&b, and if wager for way more than $40 a night. So the pay is the giant reduction in cost. Financially, they would probably come out ahead if they put the dog in a kennel and rented out the house. Instead they’re offering something else.

Wouldn’t be desirable for everyone, but I bet there will be some who jump at it.
